To all whom it mdy/ concern Be it known thatfwe, ERNEST E.` Lama and OSCAR KITCHELL, citfrlens' of the United States, residing at the cit voit' Chicago, in

" intended to be`i'1sed'within a garage or housing, for turning automobiles, 'after they are driven thereinto head or front first, so that they will front outwardly when a new or another trip [is begun, but which may be used in turning automobiles lor other vehi cles within or without a vgarage or housing, and it consists .in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and 'speciically claimed. i

The'principal object of our invention 1S to provide a turn-talile for any kind of Ivehicle and adapted for location within or without an inclosure, which shall be simple and inexpensive in construction, strong, durable, self-acting in both directions, that is. when loaded or unloaded with a vehicle,4 and efficient in operation.

Other objects and advantages of the in vention will be disclosed in the subjoined explanation and description. Tn the4 accompanying drawings, which serve to illustrate our invention Figure 1. is a, plan view of the turn-tablo showing it located within an inclosure or garage, which latter is shown in section, and illustrating thc supl'iortingplatform or table in the position it will occupy after the vehicle has heenv driven thereon and turned half way around so as to tace the opening in the in' closure; Fig. 2 is a sectional view partly in elevation taken on line 2--2 of Fig;- l., look ing in the direction indicated by the arrows, showing the positions the parts will occupy when the supporting table or platform and thcvvchiclc thereon has been turned half way around t0 permit of the vehicle being driven or moved Afrom the tablc; fll`ig. 3 is a plan view of the base of thc apparatus, showing the 'surrounding housing therefor in section, and illustrating thc turn-table or supporting platform removed; Fig. 4 is a central sectional-view taken on line ll-Ll of rig. l, looking in the direction lindicated by the arrows, showing the supporting table or platform in its elevated position, or that po sition which it will occupy before the ma chine is driven thereon, in other Words, in its initial position; Fig.` 5 is a sectional .View taken online 5-5 of'Fig. 8, looking in the direction indicated by the arrows, but

illustrating a portion of the supporting tau bleor platform with *the releasing and start ing mechanism therefor in enga ement with the etop for the releasing mec ianism and v:the starting device; F ig. 6 is a lcross sectional view througlrthe central portion ofV the turn-table and a part of thelooror base therefor, showing a modification in the con struction of the supporting table or rotary platform and in the construction ofthe base plate therefor, and Fig. -7 is a fragmental plan view yoi the base plate constructed according to said invention.

Corresponding numerals of reference refer to like parte throughout the different views of the drawings:

Referring now to Figs. l to 5 inclusive -of the drawings, the reference numeral 10 des ignatcs the walls of an inclosure such as a garage, which may be of the ordinary or any preferred construction, but preferably rectangular in shape, as shown, and provided 1n one of its walls with a doorway or opening ll, extending from the ground 12, upwardly, through which opening the automobile iuay he driven into the inclosure.y

As is clearly shown, the ground or floor 12 1s provided with a depression or pit 13, into which the lower kportions of the walls l()4 Wil which may loe made o'f any suitable matcrial and shape, but preferably circular to fit within the pit 13, which is also preferably circular, and has at the entrance or approach 'l1 to the turn-trible, as well as at the roar portion thereof, a horizontal door iii, the

Of course` il: desired, the pedal bar 46 may be pressed dowiiwardhf by means of thefootiinstead'of by .n'leans ot the wheel of the` vehicle,4 as nlmve explained, but in either way it will be seen that the roller 49 will assist in starting tl revolution oi` lh" platform or table. n' the table with the .vehicle thereon has been automatically turned joue-half way around, as above set forth, it evident that the jlront ol the machine onvehicle will fare She opening ol. the garage or approach to the im-n-l;alile, and that the 'vehicle ,may be driven therefrom, when, by reason otn the 'tion oi the spring 35. the tension of which has been increased by the turning of the platfornl, said platform will be rotated backwardly a half turn, thus causingr the rollers lit and -l-ll to travel upwardly on the inclined tracks until the releasing lever l2 engages the calici E37 therefor, when the table will la ecked in position 'for the vehicle to he again in thereon.

in the abovedescribed construction the ,lined tracks are and have been described inn; mounted 'on the liaise, and the roll- -iieinn' carried by the turn-tal'ile or im but this arrangement .may be red, and, in lliggfs. (l and 'l o'l the ldrawings e have shown a modification in which the fr ,iiatiorm 28 is provided on its ylower with outer inclined tracks 18*L and d and in ardly ol. said tracks with inclined tracks 20 and 21, which tracks are of the same construction und arrangement with respect to one another as shown in the other views ol the drawings and above described, except that they are carried b` the rotary platform instead of the base. llii this modification the base 15 has mounted on its upper surface at diamctrically disposed points brackets 37, each .of which carries a roller 38 to travel on the outer tracks of the construction shown in Fig. 6, and said base is provided on its upper surface at diametrically dis )osed points at right angles to the brackets 3 with other brackets 39, each of which has journaled thereon a roller 40 to travel on the inner tracks 20 and 21,

-ot' the rotarY platform. In this modified construction the base 15 is equipped with a retracting sprin 35, a socket 31, a rotary collar 32, to whici one end of the spring 35 is secured, a ratchet B2, and pawl 34 and for the samepurposes as in the other construction` l esidestl1e base 15"- has a beveled starting' lug` QU' and a catch 2i' for the releasing lever and its operating mechanism as in the other construction.

The platform 28 ma)l be provided with openingsI 51. having removable covers 52, through which openings access to the mechanism located between the platform and the base may be had by removing the covers for the purpose of repairinglr or adiustim: saidv mechanism.

In order to hold the `platform 28 against rotation after il has turned to about the 100 position shown in Fig. 1` and the brackets of the rollers have lstruck the bull'ers the hase 15 is provided with an upwardly cxtended spring arm 53 (see Fig. 2), having a hook or catch at its upper end to engage theI catch 5l. on that end of the lever 42 opposite the recess Alil therein Having;r thus fully described our invention what we claim as new and desiri` lo secure bv Letters Patent isl.
